What are epidermal dendritic cells?
Langerhans cells
Which of these does not belong Langerhans cells epidermal dendritic cells keratinocytes immune cells?
Keratinocytes
Which cell is known as antigen presenting cell?
Dendritic cells,macrophages, B cells
What cells engulf antigens and present fragments of them on their own surfaces where they can be recognized by cells that will deal with them?
dendritic cells
What are white blood cells found in the epidermis that phagocitize mircrobes?
I believe they are the myeloid dendritic cells called Langerhans cells.
What type of lymphocyte is concentrated in the germinal centers?
3 types: Dendritic cells, B cells and CD4+ T cells.
Where in the lymph node do the T cells first encounter antigens presented by dendritic cells?
deep in the cortex.
Are Macrophages and Dendritic cell the same?
Both macrophages and dendritic cells are formed from the same precursor cell, the monocytes. However, the two cells serve different functions during an infection. Macrophages remain in the area of the infection and phagocytosis (engulf) foreign invaders and dead cells. Dendritic cells leave the infected tissue and travel to local lymph tissue in order to alert the adaptive immune system.
What are the skin macrophages that help activate the immune system?
Epidermal dendritic cells
Specialized white blood cells that patrol the body searching for antigens that produce infections are known as?
Dendritic cells
Phagocytic cells that occupy the epidermis are called?
The epidermis contains phagocytic cells called DENDRITIC CELLS. The slender, fingerlike processes of dendritic cells extend among the surrounding cells, forming an almost continuous network to intercept invaders.
What cells express MHC class II molecules?
There are two classes of MHC. MHC I are expressed in all cells except red blood cells (because they lack nuclei). MHC I andMHC II are expressed in professional antigen presenting cells (APC's) that include :macrophages, dendritic cells and B cells.
